Then let us propose a wild theory. The Old Man himself had a telepathy ball. Only this one was better and had memories of the future, and gave Motavian lottery numbers... for events 500 years later. It also told of the Great Uncataclysm of 236X AW, when Motavia became nice and cheery again, for no reason, where people were all like, "We have food! Awesome!" and there was a massive amount of candy... and the Old Man never told a soul.
But seriously, what if "This is a treasure that has been passed on generation after generation" is really just a more flattering way of saying "Yeah, I looted this from a treasure chest a while back! Isn't it awesome?"
